ANTISEPTIC MOUTHPIEOE FOR TELEPHONES, SPEAKING-TUBES, &c.

Specification of Letters Patent.

Patented Oct. 6, 1908.

Application filed April 7, 1906. Serial No. 310,566.

To all whom it may concern:

Be it known that I, MILTON S. HUF- sonM nT, a citizen of the United States of America, and a resident of the city and county of San Francisco, in the State ofCalifornia, have invented a new and useful Antiseptic Mouthpiece for Tele hones, S eaking- Tubes, and the Like, of w rich the ollowing is a specification, reference being had therein to the accom anyingdrawin i As is well nown, it is hefil by physicians generally that, on account of the frequent use of telephones and other voiceinstruments by different persons who speak and exhale their breath into the mouthpieces thereof,the erms of disease are, or may be, transmitted from one person to another.

It is therefore one of the objects of th present invention to provide an antiseptic mouthpiece, simple in its construction, which will readily absorb any moisture from the breath and immediately destroy disease germs or any other micro-organisms which may lodge in the mouthpiece, as well as to perfectly deodorize the same.

Another object of the invention is to provide a sanitary mouthpiece which can be used indefinitely by the application of an antiseptic solution from time to time.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

in the accon'ipanying drawing, Figure 1 is a sectional elevation of a telephone mouthpiece embodying the invention. Fig. 2 is a plan of the same. Fig. 3 is a perspective Vi(\\ of a perforated metal disk comprised inthis improved mouthpiece. Fig. 4 is a similar view of a perforated disk of felt used in connection with the said metal disk. Fig. 5 is a sectional elevation of themouthpiece similar to Fig. 1, but comprising a i'fietal disk of modified construction. Fig. 6 is a erspective view of the latter named metal isk.

Like numerals of reference dcsignate'like parts throughout the different views.

1 represents an ordinary mouthpiece for telephone transmitters, which is formed with a screw thread 2 to engage with a corresponding screw thread in the transmitter of the usual constrluztion. N car its inner end, the mouthpiece, which is preferably trumpet shaped, is provided with a transverse partition, 3, having a series of perforations 4, as usual.

The lining 5, which constitutes part of the invention, is made of'felt or other suitable- 'flange 6, which fits snugly around and over the edge of the mouthpiece.

At the bottom of the mouthpiece, and resting upon the partition, are two ormore perforated washers or disks 7, preferably made of material similar to the lining 5. The per forations 8 in the disks are made to register with the perforations in the partition so as ,to allow the sound to pass freely into the transmitter. A metal disk 9, also perforated in a similar manner, with the exception of two threaded screw holes 10, holds the disks 7 in position by screws 11 passing through from the under side of the partition 3 as shown. The disk 9 is preferably made large enough to engage with the lining 5 and hold the same firm at the bottom.

In the modified form shown in Figs. 5 and 6, the disks 7 are held in'position by a perforated metal disk 12, formed with teeth 13 in its upturned. outer periphery 14.. The disk is made large enough to embed its teeth in the lining 5 and prevent the washers 7 from changing their position when the disk has been forced down upon them. The mouthpiece thus lined at the sides and at the bottom is ready to receive an antise tic or dis infectant solution, which is app ied to the lining from time-to time in any desired manner. The material of the lining being of a.

yielding or non-resonant nature will prevent the vibrations of the voice being taken up by the material of the mouthpiece and transmitted to the diaphragm in interference with the regular vibrations transmitted to the diaphragm direct through the perforations in the partition and disks.

' Having described my invention, 1 claim:

1. A month piece comprising hollow body, a porous disk extending transversely across the interior of the same, and a perforaiedmetallic plate located over said dish.

2. A mouth piece comprising a hollow body, a porous disk extending transversely across the interior of the same, and a perfo rated plate located over said disk and having an upturned engaging edge.

3. A month piece comprising a hollow body, a porous disk extending transversely across the interior of the same, and a erforated metal plate located over the dis and having a serrated engaging edge.

4. A month piece comprising a hollow body, a porous disk extending transversely across the interior of the same, and a metallic plate located over said disk and having an upturnedserratedengaging edge.

5., In a mouthpiece of the character described, a hollow trumpet-shap ed body adap ted to be secured to a transmitter and provided with a perforated partition, a lining of felt extending from the partition to the rim of the body, perforated disks of felt upon the partition, a perforated disk secured upon the felt disks, and means for fastening the outer "portion of the felt lining in position.

6. In a mouthpiece of the character described, ahollow trumpet-shaped body ad ap ted to be secured to atransinitter and provided with a perforated partition, :1 lining of felt extending from the partition to the outer edge of the body, perforated disks of felt upon the p artition, a perforated disk of metal upon the felt disks having its periphery turned up and provided with teeth adapted to engage with the lining, and means for securing the outer end of the lining in position. In testimony whereof l Lilli); my signature in presence of two witnesses.
